Reliability and Validity Paper

The profession of human service uses an enormous quantify of information to conduct test in the process of service delivery. The data assembled goes to a panel of assessment when deciding the option that will best fit the interest of the population, or the experiment idea in question. The content of this paper will define, and describe the different types of reliability, and validity. In addition display examples of data collection method and instrument used in human services, and managerial research (UOPX, 2013).
Types of Reliability
Reliability is described as the degree to which a survey, test, instrument, observation, or measurement course of action generating…show more content…

External refers to the degree to which the product of the research takes a broad view further than the example. Face validity is related to scientific method. It is highly concern to determine whether or not the instrument measure what is declaring. Internal validity take into account the independent variable of the research, which can correctly affirmed to construct the observed result expected. Statistical is the extent to which the ending of the research report, or score is reliable, or convincing.
Furthermore, to obtain the result of reliability, and validity a process of study should put into action on the gathering data and how the data is use to perform, and manage the study according to plan. These examples of reliabilities mentioned-above are degree to which recurring measures under unchanged condition demonstrate the same outcome (Reshow & Rosenthal, 2008). The information gathering approach pertaining to reliability and validity are decided by products that are simple to understand, evaluate, simplify, and linking to the hypothesis.
Data collection methods play an essential function in human services because of the influence it has on the data applies to identify the procedures relating to the monitored results. Three common are often used are group focus, written records, and survey. These examples help to determining any possible modification

chapter 6: Measurement
1. The difference between reliability and validity of a measure. Example.
They are all important qualities of measurement. Reliability means the degree to which a measure yields consistent results. Eg: Using a scale to measure a rock’s weight, the scale would tell its weight with reasonably reliable measurements whenever it measures. Validity means the degree to which a measure taps what we think it’s measuring. Eg: Like measuring the rock’s weight, no matter how valid the…

classification and diagnosis of schizophrenia
The two issues surrounding classification and diagnosis of Schizophrenia are reliability which means getting the same or similar results when repeating a study or a test and validity which simply means whether the test is measuring what it is supposed to measure.
One of the ways schizophrenia can be diagnosed is test-retest reliability. Cognitive screening tests e.g RBANS can be performed. This test is important when diagnosing schizophrenia as they measure…

Evaluating Truth and Validity Exercise
The arguments I will choose to evaluate for truth and validity will be taken from the Applications list 12.2 (a.-y.) at the end of Ch. 12 in The Art of Thinking. I will start with exercise j and the premise that “power must be evil because it can corrupt people”. First of all, I would check the argument for any hidden premises making sure that it was stated fully and in a clear way. This argument seems to pass the first hurdle, however when it comes checking…

According to Parahoo (2006), in quantitative studies reliability and validity are two of the most important concept used by researcher to evaluate the quality of the study that is carried out. Reliability and validity in research refer specifically to the measurement of data as they will be used to answer the research question. In most cases, the instrument that measures the variable is the central issues in determining the reliability and validity of the data. Whatever data collection method is used…

Reliability of Results for the Clerical Test and Work Samples
Before interpreting the reliability results for the clerical test and work sample it is a good idea to first define what reliability of measurement is. A measurement is reliable to the extent that it provides a consistent set of scores to represent an attribute. In the majority of the case perfect reliability is never achieved because of the errors that the distinct types of measurement have. If we test the same time more…
